AMD Renoir driver tries to identify the presence of DMIC by evaluating ACPI _WOV entry, and it returns -EINVAL when the ACPI call failed. This ended up an error message like snd_rn_pci_acp3x: probe of 0000:04:00.5 failed with error -22 although the system is correctly set up. For avoiding such a superfluous error message, change the return value to -ENODEV. Then the driver core just skips to the next one without complaining.
